A couple of minor bomb issues

[Phasma Felis]

Were the thrown-object physics changed in this version? Used to be that if I pressed against a wall, crouched, and threw a bomb, it would reliably excavate two squares horizontally, but now it only gets one. It's looks like it's bouncing a few pixels farther back from the wall, compared to before.

On the subject: It doesn't seem to be possible to throw objects upwards when there's a roof directly above. This is annoying when you've got stickybombs and are trying to tunnel upwards. This was true in previous versions, I know.
